Question
Given below are two statements: Statement I: Benzoic acid produces effervescence on treatment with aq. . Statement II: The effervescence is due to the release of hydrogen gas. In the light of the above statements, choose the most appropriate answer from the options give below:
Both Statement I and Statement II are correct.
Both Statement I and Statement II are incorrect.
Statement I is correct but Statement II is incorrect.
Statement I is incorrect but Statement II is correct.
Carboxylic acids (like Benzoic acid) are stronger acids than carbonic acid (). Consequently, they decompose carbonates and bicarbonates to evolve carbon dioxide gas (), which produces brisk effervescence. The reaction is represented as: . Therefore, Statement I is correct because the reaction occurs, but Statement II is incorrect because the gas released is , not hydrogen ().
This question aligns with the NEET CHEMISTRY syllabus, specifically targeting concepts from Aldehydes, Ketones and Carboxylic Acids. Mastering this topic is crucial for scoring well in the upcoming medical entrance examinations.
